The RAFS input voltage is 22 V to 26 V or 8 to 12 V and is connected through a 15 pin sub-D and 2 SMA connectors. The magnetic field sensitivity of less than 2 × 10-13/ Gauss is enabled by using a double magnetic shield. The RAFS is available in 10 MHz only, and has an extended Rubidium lamp life of more than 20 years.

Temex Components announces the availability of a new Rubidium atomic clock, the RAFS series that is approved by the European Space Agency for use in the Galileo Global Navigation System. The RAFS has a very low temperature sensitivity, required for radio-navigation applications, of less than 1 × 10-13/°C. This was accomplished by utilizing a double oven construction with a high stability SC cut crystal oscillator. The RAFS exhibits excellent short-term stability of less than 5 × 10-14/10,000 sec. And drift of less than 3 × 10-13/day. It's long term stability of less than 1 × 10-10 for the first year, is controlled by a systematic burn-in and pre-aging process. The RAFS is suitable for ground or space use. Applications include navigation satellites, military communication satellites, tracking and guidance control, and advanced low orbit digital communication satellites.
